This book was released on 1971 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: A refined Karman-Pohlhausen method previously generalized by Zien to include the effects of mass transfer is further explored and its application is extended to cases involving both pressure gradients and surface mass transfer. The case with piece-wise suction (or blowing) is also included. The study is restricted to plane, incompressible, laminar boundary layers. Configurations of flat plates and circular cylinders are chosen to illustrate the application of the method. Results are given mainly in terms of skin frictions, and they are presented entirely in closed forms. The calculations for the porous plate case are carried out using rather elaborate velocity profiles, but the results differ negligibly from previous ones with very simple profiles. A linear velocity profile is then used to carry out some exploratory calculations for more complex flows. The method is shown to be a potentially efficient tool for handling the problem of boundary-layer control by means of surface mass transfer. (Author).

This book was released on 1972 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the incompressible turbulent boundary layer, developing under the combined effects of mass transfer and pressure gradient, is presented in this paper. A strip-integral method is employed whereby two of the three governing equations are obtained by integrating the combined momentum and continuity equation to 50 percent and 100 percent, respectively, of the boundary-layer height. The latter equation is the usual momentum-integral equation; the former equation requires specification of shear. Accordingly, Clauser's equilibrium eddy-viscosity law is assumed valid at this point. The third and final equation is obtained by specifying that Stevenson's velocity profiles apply throughout the domain of interest, from which a skin-friction law can be derived. Comparisons of the numerical results with the experiments of McQuaid, which include combined effects of variable pressure gradient and mass transfer, show good agreement.

This book was released on 2012-02-26 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents contemporary theoretical methods in fluid flow and heat transfer, emphasizing principles of investigation and modeling of natural phenomena and engineering processes. It is organized into four parts and 12 chapters presenting classical and modern methods. Following the classical methods in Part 1, Part 2 offers in-depth coverage of analytical conjugate methods in convective heat transfer and peristaltic flow. Part 3 explains recent developments in numerical methods including new approaches for simulation of turbulence by direct solution of Navier-Stokes equations. Part 4 provides a wealth of applications in industrial systems, technology processes, biology, and medicine. More than a hundred examples show the applicability of the methods in such areas as nuclear reactors, aerospace, crystal growth, turbine blades, electronics packaging, optical fiber coating, wire casting, blood flow, urinary problems, and food processing. Intended for practicing engineers and students, the book balances strong formulation of problems with detailed explanations of definitions and terminology. Author comments give attention to special terms like singularity, order of magnitude, flow stability, and nonisothermicity characteristics. More than 400 exercises and questions are offered, many of which divide derivations between you and the author. For these exercises, the author describes the solution method and the results in the text, but you are directed to complete specific portions of the solutions. You then have a choice to accept the results or to further explore the underlying problem. Extensive references are provided for further study.

Book excerpt: Coanda effect is a complex fluid flow phenomenon enabling the production of vertical take-off/landing aircraft. Other applications range from helicopters to road vehicles, from flow mixing to combustion, from noise reduction to pollution control, from power generation to robot operation, and so forth. Book starts with description of the effect, its history and general formulation of governing equations/simplifications used in different applications. Further, it gives an account of this effect’s lift boosting potential on a wing and in non-flying vehicles including industrial applications. Finally, occurrence of the same in human body and associated adverse medical conditions are explained.

This book was released on 1960 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report the integral method is employed to investigate some effects of compressibility, heat transfer, mass transfer, and streamwise pressure gradient in boundary layers over slender bodies of revolution, where the boundary layer thickness is not necessarily small compared to the body radius. The results for zero pressure gradient without mass transfer are compared with those of other investigators in the low-speed case and in the adiabatic-surface case. These flows generally produce nonsimilar profiles. A special case of zero pressure gradient with mass transfer, which yields a similar solution, is solved. For flows with and without pressure gradients and mass transfer, special conditions which produce similar profiles are derived. For low-speed flow with no mass transfer but with pressure gradients, a set of nonsimilar soultions is presented.
